ATOMIZE'YR.

SPECIFICATION forming of :Letters Patent No. 587,890, dated August 10,1897.

Application filed January 11, 1896. Renewed October 9,1896. Serial No.608,422. (No model.)

I To all whom it' may concern.-

cungie, Pennsylvania, have invented certain new and useful Improvementsin Atomizers,

of which the following is a specification.

My invention relates to a new and useful 7 improvement in an apparatusfor spraying liquid poison upon plants ortrees for the purpose ofexterminating insect life; and with this end in view my inventionconsists in certain details of construction and combination ofelementshereinafter set forth, and then spe cifically designated by theclaims.- It is well known that great injury is occasioned to certainplants andtrees on account insect life by the use of-liquid poison, butwith little success on account of the liquid being applied ina body orin such coarse spray asto form drops upon the leaves and fall therefrom,thus leaving a large portion of the plant unaffected, so that but asmall proportion of the insects are destroyed,while at'the same anapparatus as toapply the poison in an exce'edingly fine vapor, whichwill completely envelop the leaves of the plant and fall thereon muchafter the manner of dew, so as to aifect every part thereof, thuscompletely exterminating the insect life.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction and operation in detail, referring by numbers to theaccompanying drawit ings forming part of this specification, and inwhich- Figure 1 is a central vertical section of the tank or reservoirof the apparatus, operating parts being in. elevation. Fig. 2 is a planview, andFig. 3 is an elevation showing my improvement adapted to beused upon a reachpole in order that access may be had to the branches oftrees and the like. Similar numbers-denote like parts in the severalviews of the drawings.

1 represents the tank or reservoir, in which isarranged an agitator 2,consisting of any suitable number of blades secured to a vertical shaft3, which latter is journaled in said tank and projects throughthecoverithereof. 4 is a drum secured upon this shaft and having coiledtherein a spring 5, one end of which is attached to the drum and theother to the top'of the reservoir.

6 is a cord which is secured to the periphery of the drum and adapted tobe wound thereon and unwound therefrom when the movable member of thebellows 7' is operated. This bellows may be of ordinary construction,consisting of two handles by which the apparatus is supported andoperated, and leading 'th'erefrom is a tube-8, which passes upwardparallel with the side of the tank and termi-.

nates in a nozzle 9.

10 isa small tube which leads from belo the surface of the'liquid withinthe reservoir into the tube 8 and is bent parallel therewith,terminating in a small orifice just inside of the opening of the nozzle.

11 is an inlet whereby air is supplied to the reservoir'above thesurface of the liquid in order to prevent a vacuum therein, and 12 isvalve having a hand-wheel 13, by means of which said valve may beoperated. This inby induction, assisted by the pressure above descFibedcreated upon the surface of the liquid, will cause said liquid to risein the tube 10 and issue in a smalljet from the orifice, where it willcombine with the air in its passage from the nozzle, said air holdingthe liquid in suspension, as does the atmosphere moisture under certainconditions, so that it is only necessary to direct the flow of envelopedby the moisture drawn" from the reservoir. During this operation of thebelthe air from the nozzle upon the plants to be 1 .,treated, when saidplants will be completely let leads from the tube 8, so that by theproper .4

From this description theoperation of my lows-handle the-cord 6 will bedrawn to and fro, causing the agitator-bladesto be mvmea back and forthwithin the liquid, thus preventing precipitationof the poison elementtherein. e I a It sometimes becomes desirable to treat trees and vinesin the manner j ust described, in which case I arrange my apparatus upona reach-pole 14 and providea foot-bellows 15, which is connected to thereservoir by means of a rubber or other-flexible hose 16, in which caseI also find it desirable to operate the agitator separate from thebellows, and I therewith provide a hand-lever 17, which is connected bya cord 18 to -the drum, as above described. By this arrangement theoperator is'enabled to 'bring' the nozzle of the ap--' paratus inproximity to the branches of a tree of con'siderable height, and he thenoperates the bellows by pressing his foot thereon and the agitator bybearing upon the lever 17. Any of the well-known liquid poisons may beused, such as aris-green dissolved in water.

Having thus fully described my invention, what I claim as new and usefulis 1. In an atomizer, a reservoir having jour naled therein a shaft, anagitator secured to said-shaft and adapted to revolve therewith,means-for revolvingsaid shaft, the tube 8,extending across the upperportion of the reservoir, the tube 10, leading from the bottomof thereservoir and terminating within the tube 8, axially therewith, anair-inlet leading from the tube 8 into the reservoir, a valve forcontrolling said inlet and'a bellows adapted to 35 supply air to thetube 8 under pressure,'whereby the liquid in the reservoir is elevatedthrough the tube 10, and commingled with the air issuing from thenozzle, substantially as and for the purposes set forth.

2. In a device of the character described,

'areservoir, a shaft journaled within the reservoir, an agitator on theshaft, a drum secured on the end of the shaft, a coil-spring connectingthe drurnto the top of the reservoir, a tube leading upward from thelower part of the interior of the reservoir to the top, a pipe inclosingthe end of the tube, *ati outlet from said pipe'leading-into the reser-I voir and means for supplyingthe"pipewitli 50 air under pressure andfor revolving the drum against the action of the coi l spring,

and for the purpose described;

In testimony whereof I have scribing witnesses,
